Specification of Letters Patent.

Patented Dec. 28, 1920.

Application filed February 10, 1916. Serial No. 77,441.

To all whom it may concern:

Be it known that I, HENRY A. HoUsE, J r., a citizen of the UnitedStates, residing at Long Hill, in the county of Fairfield and State ofConnecticut, have invented certain new and useful Improvements inDetachable Wheels; and I do hereby declare the following to be a full,clear, and exact description of the same, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings,

I and to figures of reference marked thereon,

which form part of this specification.

Like figures of reference refer to like parts.

This invention relates to detachable wheels and particularly to thatclass thereof which have hubs composed of inner hubs and outer hubshells.

The inner hub of this class of wheel, whether the wheel be a driving ora driven wheel, is designed to remain engaged with its axle or shaft andis held against longitudinal displacement thereon, while the outer hubshell is removably attached to and co-fits with the inner hub.

One object of the invention is to provide a hub structure of the abovecharacter with an arresting means, which is so constructed, as to permitthe outer hub shell to move freely over the inner hub, when in onerelation thereto, and which prevents the outer hub shell from moving offfrom the in ner hub, when in another position, relative thereto.

Another object is to provide such a hub shell arresting means that willremain in operative relation under running or standing conditions andwhich can be released only upon jacking up the axle of the arrestedwheel to free the hub shell from the weight of the vehicle.

Another object of my invention is to provide means for relieving theholding nut threads of direct transverse pressures, and to carry theseforces elsewhere between the hub parts.

Another object of the invention is to provide a hub structure of theabove character, with means for mutually supporting the hub sections ateach end and wherein one of said supporting means includes devicesmovable longitudinally of, and outwardly radially to the hub sections,into position, for holding the same in assembled position.

Afurther object is to provide such antiturning means, as can be madetight by the clamping action of the holding nut, regardless of wear ofthe contacting surface of said anti-turning means, in a manner to haveas near a continuity of contact between said surfaces, as is practical.

A further object of the invention is to provide a hub structure of theabove character, wherein the movable devices for holding the hubsections in assembled position shall, when in released position, permitthe outer hub shell to passoif from the inner hub.

A still further object of the invention is to provide a hub structure ofthe above character, wherein the devices for securing the hub sectionsin assembled position are movable with respect to the hub, by anoperating member which is retained on the inner hub section, when thedevices are in released position.

A further object is to provide means for limiting the outward movementof the holding nut with relation to the inner hub member.

These and other objects are hereinafter referred to and will be morefully disclosed.

each of said in I tuchec. by k in it one set 11111211 an inturned flange35 on the inner end of the nut 18, adapted to engage a hook 36, having abase 37 screwed to the inner .hub 4 by screws 38.

The dotted position of the outer hub shell and attached parts is thattaken relative to the inner hub when the nut is removed, or lost, andthe weight of the vehicle, provided with such a hub, is the engagingforce. The result here represented is hereinafter described.

In Fig. 2, the end view of the outer hub shell 3, shows the inturnedflange 10 and the corrugated conical recess 13, with its corrugations13.

In Fig. 3, the end view of the inner hub shows its small conical end 21,recessed at 26. are the inside threads, 12 is the corrugated annularprojection with corrugations 12. 11 is the other annular projection.

In Fig. 4, is shown the eccentric and caught position of the hub parts 3and 4, whereby the inturned flange 10 occupies the recess 4 and at 39engages the annular -shoulder formed by the projection 11, contactingthe neck at 40. The corrugated annular projection 12, occupies the space10. The small end of the inner hub 4 is shown contacting the inner wallof the outer hub shell 3, at 41. The eccentricity of the parts isfurther shown by the relative position of the axes of the said hubparts. A'-A is the axis of the inner hub and B-B that of the outer hubshell.

In Fig. 5, 5 is a section of the axle. 6 is one of the ball bearings. 11is an annular projection on the inner hub 4, and 10 is the inturnedflange of the outer hub shell 4, here shown eccentrically enveloping thesaid projection 11. the inner edge of the flange 10 contacting the neckat 40.

In Fig. 6, the nut 18 is shown partially unscrewed from the inner hub 4,and in such a position as to cause the inturned flange to engage thehook 36. The segmental ring 15, in hooked engagement with the annularprojection 16, is shown contracted, by the spring 19 and near theextreme end of the conical part 21, of the inner hub 4, it 0011- tactsthe inner hub 4. The ring 15 is shown to be contracted by the spring 19to come within the lines F-F, which lines are parallel and drawntangcntto the inner surface of the smallest part of the neck of the outer hubshell 3. The contracted outside diamctcr of ring 15, being thus lessthan that of the inside of the smallest part of the neck of the outerhub shell. 3, permits the free taking off of the said hub shell 3,during the threaded engagement of the nut 18 with the inner hub 4.

In Fig. 7, the hook 36 extends from the curved base 37, which isprovided with assembled elements 15 of the ring 15.

threaded holes 38, adapted to engage screws 38, shown in Figs. 1 and 8.

In Fig. 8, the connection of the spring coil 31 with the bolt 22 isclearly shown. The slot23 is adapted for sliding engagement with therivet 23, shown in Figs. 1 and 6.

In Fig. 9, is shown the wrench adapted for use with the nut 18 and itscap 32. 42 is a fragment of the handle, 43 is a disk, integral with thehandle. Upon the disk 43 is a hexagonal boss 44, having a circularrecess 45 with a beveled edge 46. The boss 44 is adapted to enter therecess 30 in the nut 18. For taking off the cap 32, pins 47 and 48,projecting from the disk 43, form therewith a spanner wrench forengagement with notches 34in the cap 32, shown in Figs. 1 and 15.

In this Fig. 9, fragment of the nut 18 is shown dotted, to represent therelative position of the boss 44, with reference to the nut and itslocking means, when the wrench is fitted into the recess 30 of the nut18. The arm 29", with the bolt 22, shows the depressed position taken bythe bolt 22 and its arm 29, when the arm 29 engages the circular recess45, of the wrench. The beveled edge 46 assists in depressing the arm 29,as it enters the recess 45. The end 24 of the bolt 22. is here showndepressed below the threads 25, allowing the free turning of the nut 18by the wrench.

In Fig. 10, the segmental ring 15 is shown in elevation to be closed andheld by the contracting spring 19. I

In Fig. 11, is shown the hook ends, 15?, of The position of the spring19 within the annular groove 20 is also shown.

In Fig. 12, the expanded position ofthe assembled segments 15", of thering 15, brings the hook ends 15 of said segments 15 into view. and alsoshows the peripheral spacing of the segments 15 in this expandedposition. i

In Fig. 13, the side elevation of half the ring 15. shown in Fig. 12.clearly shows the internal, construction of the segments assembled inexpanded position and. surrounded by a spiral spring 19.

In Fig. 14, a split spring coil 19 is shown as a substitute for thespiral spring 19, and occupies the groove 20 in the segment 15".

This coil 19 is made of such a diameter, that Cit 50, so as to passconcentrically orer eliou' 50 when. ta king off the hub shell In tlinm'e the hub parts 3 and -fl. are shown in their ce-litting position,and clamped lengitudinally by the expanded se mental rii'ip; 15.

In Fig. 3.6, is shown the eccentric engagement of the modified form ofhub shell arresting means, comprising the elements l9 and 50 shown inFig. 15.

In use, referring to F 1. the inner hub 42 is first journaled on theaxle write the ball bearings 6 and. 7 and is lined longitudt nallythereon by means of the nut The outer hub shell 3, is built attached tothe rim 1 by means of the spokes 2, so that the rim 1 and spokes 2 go onor oil" *th. the outer huh shell. tar the d iacliah e feature of thewheel is concerned, the in ier hub 4 is allowed to remain on the axleafter sli iping the wheel elf. After journa 1 ing and fixing the innerhuh l, long i udi nally, upon the axle the rest of the wheel ispositioned by slipping the outer huh shell into co-tittingr positionwith the inner hula 4. The outside diameter of the ennui VS uni Jprojection 11 is adapted. to p: 10. The corrugations ot the conicalcor".- g'ated surfaces of the respective annu 1 projection 12 and theannular recess 1. come inter-meshed, and at the same time center thelarge end of the oute huh shell upon that of the inner huh 4. .hmu l.the intermeshed corrugations ot tion 12 and the recess 13 is transindriving or rotating force; in th rear wheels the inner hubs dri while inthe case of the trout winireverse is true and the wheels rotate nerhubs.

The nut 18, hearingthe segmenta 15, is next threaded with the A. wrenchis next positioned. hr: 41.4; engaging the recess 30 of shown in Fifi.9. During the arm 29 ano the bolt a. so that the end 24. oi? the threadsAs the wre ch is ti screw on the nut. the beve ed ends al end ments ofthe ring" engage the on w tuereoi 21 of the inner hub 4; and expand andmore lougi'iti' muaii n unt l the ring 15 comes into enga with theconical surface of the outer h shell A further mo ement of tl. inwardcauses a drawing: togret parts 3 and 4. Upon wi wrench, the end 24: ofthe ho? to e gage one ot the notches molly actuated. out "ard by Thebelt 22 will engage one of 26 at the instant of registration therewitand remain in this locked position. until the Wrench is again applied toengage the iu l the hook heads 15, of the segmental ring 15, the wheel.will not come off. But if the nut 18 should be either in rel easedposition or oil entirely, the outer hub shell 3 with its attached rim 1,will start to come off and assume, relative to the inner hub l, theosition indicated by the dotted lines; 3 representing the outer huhshell, 1 the rim and the spokes. The inner edge ot the inturned flange10 will eccentrically contact the hub neck, shouldering against theannular projection 11. at the point and part way up on each side thereofand. will arrest any further longitudinal off-movement oi the outer huhshell 3, on the inner hub 4. This arrested position oi? the hub partsand 4; is better shown in Figs. 4; and 5.

Should, for any reason, the flange 1O fail o shoulder on the annularprojection 11, or 5) from such shouldered engagen1ent,then tee annularprojection 10 durinr an oft ineu-uient of the hub shell 3, on the inner1 :h i, will. shoulder with the annular pro- 'i.on 1'15, and will forman extra arrest means to prevent the detachment of the Lrr huh shell 3,from the inner huh It necessary to have the outside diameter of iannular projection. 11 a trifle smaller than the inner diameter of theannular prol --Lion ill to insure the passing of the proiwlion 10 overthe projection 11 during mural operations oi fitting the hub together,or taking them apart. i the large ends of the hub parts are so modifiedas to no longer include the hub shell arresting means, then the one setof huh shell arresting means aflorded by the use of the annularprojectirms 10 and 1.1 can he used.

llelerring to Fig. 4. it is necessary to have t space 10 greater indiameter and longiiud'ial depth, than the distance between the 1; ertace, 12, of the aimular corrugated which, if allowed to contact theinner surface of the flange 10 in the act of arresting the off-movementof the outer hub shell 3, during the running of the vehicle would becomeburred or otherwise damaged and be likely not to function properly withthe surface of the corrugated recess 13.

lVithout the annular projection 11, the flange 10 could be shoulderedwith the projection 12, but in the running of the vehicle, thecorrugated edge of the projection 12, in contact with the flange 10,might cause the projection 12 to climb out of the recess 10, by theengagement of some of the corrugated elevations 12, with the inner edgeof the flange 10.

Besides the rolling of the flange 10 upon the neck between flanges 9 and11, the inner hub 4 rolls inside the outer hub shell 3, in

a circular path, passing through the point of contact 41. It isimportant in designing the forms of the inner hub 4 and the outer hubshell 3 to have the parts so proportioned that in the arrested androlling position of the hub parts 3 and 4, as shown in Figs. 1 and 4,the axes A-A and 13-13, of the respective hub parts 4 and 3 will be aslittle divergent as possible to maintain the upright position of thewheel in this hubcaught position.

When the inturned flange 10 is designed to be used as one of the hubshell arresting elements, it is well to have the extra annularprojection 11, besides the annular corrugated projection 12, as aboveexplained, but in the forms of hub parts 3 and 4, shown in Figs. 15 and16, the hub shell arresting elements are placed forward of theprojection 12, toward the small ends of the said hub parts 3 and 4, andare numbered respectively 49 and 50, and the annular projection 11,shown in the other Figs. 1, 3, 4, 5 and 6, is dispensed with. The insidediameter of the annular projection 49 is a trifle greater than that ofthe annular projection 50, to allow the withdrawal, manually, of the hubshell 3 over and ofl from the inner hub 4.

The longitudinal spacing of the hub shell arresting elements 49 and 50should be such as to bring the corrugated projection 12 freely withinthe annular space 10, when the said elements 49 and 50 are in shoulderedengagement, as shown in Fig. 16.

Some advantage would probably be gained by having the hub shellarresting elements 49 and 50 nearer the large end oi the hub parts 3 and4 than shown in Figs. 15 and 16, so that the said elements 49 and 50,could have broader overlapping shouldering surfaces and yet have theinside diameter of the arresting projection (similar to 49) within thehub shell 3 a trifle larger than the outside diameter of the arrestingprojection (similar to 50) on the inner hub 4.

Should, for any reason, the hub shell arresting elements fail to remainengaged, as shown in Fig. 16, and the hub shell 3 should continue itsofl'-movement on the inner hub 4, the inturned flange 10 would catchonto the face 51, of the corrugated projection 12, and the flange 10,with the projection 12, would then become hub shell arresting means,giving, with 49 and 50, a plurality of sets of hub shell arrestingmeans. In conjunction with such a double set of hub shell arrestingmeans an extra annular projection like that numbered 11 in Figs. 1, 3,4, 5 and 6 may be employed to protect the corrugated edge of the face51.

The various forms of construction illustrated and described herein, maybe modifled and not depart from the spirit and scope of my invention. I,therefore, do notwish to be confined to the exact structure illustratedand described above.

Having described my invention, I claim- 1.
